摘要 目的:探讨坐位腰麻对剖宫产手术母婴的影响。方法180例剖宫产产妇按随机数字表法分成A、B、C三组( n =60),A组行侧卧位腰麻,注入1%罗哌卡因1.6 ml+5%葡萄糖0.4 ml+0.0005%舒芬太尼0.6 ml共2.6 ml后置于下肢抬高15°,左侧倾斜20°卧位。 B、C组行坐位腰麻,注射上述腰麻药后分别维持坐位1 min和3 min后置于上述卧位。记录产妇麻醉前后收缩压值,最低收缩压值,最低平均动脉压值,感觉阻滞最高平面,新生儿Apgar评分,产妇不良反应、低血压及心动过缓发生率,去氧肾上腺素使用率,一次穿刺成功率、术后头痛发生率。结果麻醉后3、5 min收缩压,最低收缩压,最低平均动脉压C组分别高于A、B组( P <0.05),B组高于A组,差异有统计学意义( P <0.05)。感觉阻滞最高平面C组低于A、B组( q =6.38,5.98, P <0.05),B组低于A组( q =6.15, P <0.05),差异有统计学意义。新生儿1 min Apgar评分C组高于A、B组( q =9.63,7.33, P <0.05),A、B组差异无统计学意义( q =0.71, P >0.05)。恶心呕吐、呼吸抑制、低血压、心动过缓发生率、去氧肾上腺素使用率C组分别低于A、B组( P <0.05),A、B组之间差异无统计学意义( P >0.05)。一次穿刺成功率B、C组高于A组(χ2=13.3, P <0.05);术后头痛发生率A组高于B、C组(χ2=4.14, P <0.05)。结论坐位腰麻注入1%罗哌卡因1.6 ml+5%葡萄糖0.4 ml+0.0005%舒芬太尼0.6 ml共2.6 ml并维持坐位3 min后置于下肢抬高15°,左侧倾斜20°卧位行剖宫产术对母婴影响小,可减轻术中低血压、恶心呕吐、呼吸抑制、心动过缓的发生、去氧肾上腺素的使用以及术后头痛发生率,同时提高一次穿刺成功率。
